Reactions of hypobromous acid with dimethyl selenide, dimethyl diselenide and other organic selenium compounds: kinetics and product formation

Selenium (Se) is an essential micronutrient for many living organisms particularly due to its unique redox properties. We recently found that the sulfur (S) analog for dimethyl selenide (DMSe), i.e. dimethyl sulfide (DMS), reacts fast with the marine oxida ...

The Mononuclear Metal-Binding Site of Mo-Nitrogenase Is Not Required for Activity

Wenyu Gu

The biological N-2-fixation process is catalyzed exclusively by metallocofactor-containing nitrogenases. Structural and spectroscopic studies highlighted the presence of an additional mononuclear metal-binding (MMB) site, which can coordinate Fe in additio ...

Proteome adaptations of the organohalide-respiring Desulfitobacterium hafniense strain DCB-2 to various energy metabolisms

Christof Holliger, Julien Maillard, Romain Hamelin, Mathilde Stéphanie Willemin, Florence Armand

IntroductionDesulfitobacterium hafniense was isolated for its ability to use organohalogens as terminal electron acceptors via organohalide respiration (OHR). In contrast to obligate OHR bacteria, Desulfitobacterium spp. show a highly versatile energy meta ...

Characterization of the electron-accepting part of the organohalide respiration chain of Dehalobacter and Desulfitobacterium

Lorenzo Cimmino

Organohalide respiration (OHR) is a bacterial anaerobic process that use halogenated compounds, e.g. tetrachloroethene (PCE), as terminal electron acceptors. D. restrictus strain PER-K23, an obligate OHR bacterium (OHRB), and D. hafniense strain TCE1, a ba ...

Organohalide respiration: variations on a common theme

Christof Holliger, Julien Maillard, Mathilde Stéphanie Willemin, Lorenzo Cimmino

Organohalide respiration (OHR) is a bacterial anaerobic respiratory metabolism that makes use of halogenated organic compounds as terminal electron acceptors. While organohalogens have been initially thought to be mainly from anthropogenic origin, thousand ...

New 2-Ethylthio-4-methylaminoquinazoline derivatives inhibiting two subunits of cytochrome bc1 in Mycobacterium tuberculosis

Stewart Cole, Andrej Benjak, Anthony Vocat, Jérémie Piton, Shi-Yan Caroline Foo, Andréanne Lupien

The emergence of multi-drug (MDR-TB) and extensively-drug resistant tuberculosis (XDR-TB) is a major threat to the global management of tuberculosis (TB) worldwide. New chemical entities are of need to treat drug-resistant TB. In this study, the mode of ac ...

Bacterial iron reduction and biogenic mineral formation for the stabilisation of corroded iron objects

Julien Maillard, Arnaud Michel Gelb

Exploiting bacterial metabolism for the stabilisation of corroded iron artefacts is a promising alternative to conventional conservation-restoration methods. Bacterial iron reduction coupled to biogenic mineral formation has been shown to promote the conve ...

Characterization of iron reduction in Clostridium acetobutylicum mutants obtained by targeted and transposon mutagenesis

Matthieu Jonas Valentin Amos

Iron reduction in Gram-positive bacteria is not well understood yet, even if it has been investigated in some extent for Gram-positive bacteria. The mechanisms involved in the delivery of electrons to a solid terminal electron acceptor like iron oxides hav ...

Towards artificial methanogenesis: biosynthesis of the [Fe]-hydrogenase cofactor and characterization of the semisynthetic hydrogenase

Xile Hu, Lichen Bai, Tao Xu

The greenhouse gas and energy carrier methane is produced on Earth mainly by methanogenic archaea. In the hydrogenotrophic methanogenic pathway the reduction of one CO2 to one methane molecule requires four molecules of H-2 containing eight electrons. Four ...

New Techniques for Ancient Proteins: Direct Coupling Analysis Applied on Proteins Involved in Iron Sulfur Cluster Biogenesis

Paolo De Los Rios, Duccio Malinverni

Direct coupling analysis (DCA) is a powerful statistical inference tool used to study protein evolution. It was introduced to predict protein folds and protein-protein interactions, and has also been applied to the prediction of entire interactomes. Here, ...
